This invention relates to couplings or unions employed for connecting the adjacent ends of two rods or the like orfor connecting al lever or the lilie to a rod or the like.

The invention has one of its primary objects to provide a coupling or union of the character illustrated which may be quickly and economically manufactured, easily installed and one which is furthermore strong and durable.

The several objects, advantages andnovcl details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings wherein;

Figure 1 is a perspective view showing a coupling constructed in accordance with this invention.

Figure 2 is a transverse sectional view taken through the coupling before the same is completely assembled.

Figure 3 is a sectional View taken substantially on the plane indicated by line 3- 3 in 7 Figure 1.

Figure 4L is a similar sectional view showing a modified form of construction.

Figure 5 is a similar view showing still another modified form of construction.

Figure 6 is a perspective view showing another modified form of construction.

Figure 7 is a transverse sectional view of the structure illustrated in Figure G and Figure 8 is a plan View of the blank from which the structure illustrated in Figures 6 and 7 isdeveloped.

Referring now to the drawings and particularly to Figures 1 to 3thereof the first form of the invention will be described in detail. In these figures it will be noted that the problem is to unite or couple the adjacent ends of shafts or rods 10 and 11. For this purpose there is provided a sleeve-like element or member 12 which substantially embraces the ends of the rods 10 and 11. 'The member 12 is provided with cooperating por tions 13 adapted to impinge or be forced into engagement with the adjacent surfaces of the rods 10 and 11. These cooperating portions 13 are herein shown as inwardly extending projections formed integrally on a part of the sleeve-like member 12. For this purpose the member 12 is provided adjacent each longitudinaledge thereof with a return bend 1i which produces the pair of inwardly extending projections 13 which lie adjacent to but spaced from substantially parallelportions 15; It will benoted that the projections" 13 are inclined with reference to the substantially parallel portions 15. The portions 15 are provided with one 'or more apertures 16 andthe projections 13 with a corresponding number of apertures 17 which,

however, are preferably of larger diameter. Bolts 18 are adapted to be extended -through the aligned apertures 16 and 17 in the parts 13 and 15 and be secured in place by means of nuts 19. When the bolts 18 are inserted Vand the nuts 19 screwed into placeA the protween the parts which not only prevents relative rotation between the two rods 10 and 11 Vbut relative axial movement as well.

Relative rotative movement between the parts may be further guarded against by providino a 0roove or slot 20 in the surfaces of i' C TJ the rods 10 and 11 adapted to Vbe engaged by the proj ect-ions 13. However, it will be read.- ily Vapparent that these grooves are unnecessary and may be provided solely for the purposeof additional security.

Wvhile in the form ofthe invention just described t-he projections 13 are described and illustrated as formed integrally with the sleeve-like member llnevertheless these projections may he formed separately from this member in the .manner illustrated in Figures 4 and 5. lnjFigure the .sleeve-Alike element 12 is shown as provided with a cooperating Vmember 2.1havin`g inwardly extending projections 22,7the longitudinalredges of the member' 12 being formed with lateral extensions Q3 for engagement with the member 21. As in the previously described construction when the nuts 19 are tightened upon the bolts 18 the projections will be caused to impinge the adjacent surta-ee ot tie rod or tnbe or 11.

ln Figure a pair ot non-connected membereI 2e are provided which constitute the equivalent of the projections atoredescribed whifzh are adapted for engagement with pro jections Q5 Jnirmed on the sleeve-like member 12 and are adapted to impinge the rod 10 when the nuts 19 on the bolts 18 are tightened.

ln Figures 6 to S inclusive an embodiment olE the invention is `shown wherein a lever or the like ifiin'niing a peirt of the coupling element is adapted to be connected to a rod7 tube or the like, In this term of the invention the device is developed Yfrom a blank SO preterably stamped from sheetl metal to provide au arm 31 integral therewith. rllhe body is bent to form the substantial sleeve-like portion and the ends thereoitv are bent as at l-'l to forni inwardly directed extensions or-projections 3." A bolt 36 is passed through apertures 37 formed in the body and through slots 38 formed in the ends or projections so that when the bolt is tightened the ends will be caused to impinge the rod or tube 39 to securely clamp the member thereto and to consequently couple the arm 31 to the rod From the foregoing it will be apparent that the invention contemplates means for readilv coupling; for instance the ends of two shat i :ds or the like or a shaft or rod to a lever. The construction et the coupling member is simple and is capable of being readily stamned or otherwise formed from sheet metal. lllhilc in every instance either two projections 13 or their equivalents have been illustrated nevertheless it will be apparent that but one projection 13 may be employed and the invention will function with equal efliciency.

ln view ot the obvious modiiications ot which the invention is capable reservation is made to make such changes in the essentials and all the non-essentials of the invention as may come within the purview ot the accompanying' claims.

What l claim as my invention is:

1. ,in a Coupling, the combination. with pair of axially aligned shaft-s7 each having a longitudinally extending groove, oit a sleeve embracing the end portions ot said shaft-s, a member associated with said sleeve and inclined with respect to said. shafts and roekable to engage said groove, and means for rocking said member.

n a coupling, the combination with a t axially :ned shafts, each having a udinal groove, et a split sleeve embraeie end portions o1 the shaft-s, the longiinal edges of the sleeve having flanges,

said flanges having return-bent portions engagin g in the grooves in the shafts, and means ior forcing the return-bent portions into firm engagement with the grooves in said shaits.

3. In a coupling, the combination with a Jairl of axially aligned. shafts, each having a ong1 Ludinal groove7 oiI a split sleeve embracng the end portions of said shafts, shaft ini- )inging members associated with the longifidinal edges ot' said sleeve and adapted to yngage said shafts and being angularly arlanged with respect to each other, and means Yor varying the angular relation between said members to cause the same to seat in said grooves and firmly engage said shafts.

In testimony whereof I aliix my si gnature.

HENRY MARLES.
